AGCELERATING FOOT-THROTTLE FOR USE ON AUTOMOBILE-ENGINES.

Application filed August 30, 1917.

To all whom it may concern:

Be it known that I, PLEAS E. VINEYARD, a citizen of the United States of America, residin at TVind'om, Fannin county, Texas, have invented new and useful improvements in Accelerating Foot-Throttles for Use on Automobile-Engines, of which the following is a specification.

This invention relates to a new and useful im roved form of footpedal or foot throttle to ice used in connection with the throttle or carbureter control on an automobile engine and provides means for effectively controlling the speed of an engine by the action of the drivers foot against the foot throttle located in a convenient position on the floor of the car.

An object of the invention is to provide a suitably pivoted foot pedal arranged in connection with instrumentalities necessary to exercise a controlling relation over the throttle of the carburetor and to work in an independently conjoined relation with the present form of throttle control on automobiles, and especially in connection with throttle control on the Ford car. With the above and other objects in'view the invention has relation to a certain combination and arrangement of parts, an example of which is described in the following specifications, pointed out in the appended claims and illustrated in the accompanying drawings; wherein,

Figure 1 illustrates a perspective view of a form of automobile engine and section of flooring and steering column with accessory throttle control thereon.

Fig. 2 illustrates in perspective view an assembly of the several parts constituting the device.

Fig. 3 illustrates a side view of the pedal. Referring now more in particular to the drawings, wherein the same parts throughout are designated by identical reference vided with a carbureter and throttle control mechanism located adjacent to the steering wheel. In this instance a steering wheel 2 is provided with a means of throttle control comprising a rod 3 with an integral hand actuating lever 4. This member 3-4 is arranged alongside the steering column 5 and adapted to be revolved through a partial revolution by manipulation of the hand Specification of Letters Patent.

lever 4 by the driven' An arm 6 is fixed upon the rod 3 and pivotally connects with a between the cylinders of the engine and has connection with the throttle in the carbureter located on the opposite side thereof. This assembly of parts permits the control member 8 to move back and forth in sliding contact with the cuff 7 independently of the member 3--il-.

A foot control device comprising a bell crank 10 integrally formed with a foot pedal 11 is pivoted upon a plate 13 by suitable bearings and passes through aslotted opening formed in the floor piece of the car. The plate upon which the pedal member is journaled is secured to the underneath side of the floor in any suitable manner, and in a position convenient to the driver that 'he may reach the same with his foot. A bracket 14: is secured to the base of the engine at a point in proximity to the throttle control rod 8. A bell crank 15 is pivoted upon the bracket with a bifurcated extremity 16, the forks of which lie upon either side of and between the pin 9 and the member 8. A connecting link 18 is pivotally connected with the foot pedal member and the bell the purpose of adjusting the length of said rod. A

In the operation of this form of throttle accelerator the driver of the car is provided with the foot pedal 11 and hand control 1 for controlling the speed of his car, one of which is adapted to work independently of the other in such a manner that the driver can depress the foot pedal 11 causing the bell crank 15 to move along the rod 8 and come in contact with the pin 9, at which time the rod 8 moves forward causing the throttle to be opened by the regulated movement imparted to the foot pedal.

In a similar manner the driver of the car no
